I cannot say anything useful about the rest of Richard's post but I concur with his takeaway. So long as you get enough light on Tri-X, you will get a printable negative. At some point you will overwhelm the film to the point that it loses its full range of greys but within the extremes the film is forgiving. I set my meter at 200, err on the side of overexposure, and don't sweat the half-stops. On another point: I read somewhere that you (Thor) will be souping in Rodinal in a Jobo tank. Melanie does just that with her Tri-X roll film and swears by it, though she's using a 1:100 solution for 15 minutes with a pre- rinse @ 68F. I prefer HC-110 in the recipe I posted on the other list, because the grain is more pronounced when processing in Rodinal with constant agitation. Melanie prefers the more prominent grain. You might too but be aware how the process will contribute to how grain appears in the developed negatives. Sanders McNew www.flickr.com/sandersnyc<http://www.flickr.com/sandersnyc>
